k8s的dashboard是k8s的一個web界面的工具，可以建立多種資源或者删除資源。注意，如果三台機器挂起之後，第二次直接啟動，你的dashboard好像不能通路耶，我直接重新開機了三台機器就行了，因為我的所有元件服務都是設定的開機自啟動，避免了一些麻煩。
使用k8s的dashboard建立資源來建立一個資源，有兩種方式，第一種是按照規則填寫，第二種是上傳Json格式的檔案。
可以看到，預設是Deployment，這個很多東西估計和自己的dashboard的版本有關，是以根據自己的情況進行判斷即可。
接下來，可以多這個Deployment進行删除或者編輯配置檔案，這裡将它删除掉。
然後，可以将建立的Service删除掉，如下所示：
這裡Replica Sets也删除掉，deployment并不像RC直接去啟動Pod，它們之間的差別是deployment會啟動一個RS，RS擁有RC的百分之九十的功能，比RC的功能還多一些。
